error in Correlation Coef

i am using code

ddt=randn(10,3); ddm=randn(10,1); nd=size(ddt,2); for i=1:nd tw(i) = corrcoef(ddt(:,i),ddm);

end;

but getting error " In an assignment A(I) = B, the number of elements in B and I must be the same.

   tw(i) =
   corrcoef(ddt(:,i),ddm);   how to get rid off this error .

Answer 1

When you pass in two variables to corrcoeff the output is a 2 by 2 numeric array, not a scalar.
